Abstract
The report gives results of experiments conducted at a rendering plant to obtain data needed to design wet scrubber systems for rendering plant odor control. Scrubber performance was measured by both odor panel and gas chromatographic analysis. Experiments in a three-stage packed-bed laboratory-scale scrubber at the rendering plant evaluated solutions of sodium hydroxide and the strong oxidants sodium hypochlorite, hydrogen peroxide, and potassium permanganate. Since removal of 90% per stage was obtained with fresh alkaline sodium hypochlorite solution, this reagent was selected for subsequent longer-term tests. A three-stage packed-bed scrubber was evaluated to replace an existing incinerator being used to treat a process air stream that contained from 5000 to 50,000 odor units. A week-long test with the scrubber gave a lower-than-expected average odor reduction of 85%. Data was obtained on chemicals consumption and effect of flow variables on odor removal; these data were used to update computer models that can be used to design scrubbers for odor removal.
